This invention relates to anattachment-"for the shaft of an inkingroller in a newspaper printing press:

The present applicationis a Continuation in part of my pendingapplication Serial No. 86,186,

filed April 8, 1949, and'now-aba'ndoned; Claims pounds. They are mountedas is well known in the art todistribute and spread the ink on an inkdrum, to transfer theink from the ink drum to intermediate distributorrolls, andfinally to transfer an ink film from the latter to the pressplate cylinders. There are several inkingrolle'r's in one press unit andall of them are more or less I frequently removed from the machine forrepair and replacement. Therubber facing may 'need to be re-surfaced;the roller may require truing or grinding; indentations may have injuredthe surface and require removal; a paper web may break and becomewrapped around the rollers;

the rollers may need re-setting for adjusting the c contact pressureagainst a cylinder or drum. For 1 any one or more of such reasons aninkingroller is removedfrom time to time from its supporting brackets inthe press.

The comparative frequency with. which inking rollers are removed andinstalled have heretofore made :the mounting of the same at. particularproblem with reference to the bearing. supports for the roller. shafts.1 I ,The usual support consists of a bracket'h'aving a socket with asplit bushing therein to receive the end of aroller shaft. .The upperhalf .of the bushing is mounted in a cap member-which is held clamped toa lower half of the bracket to holdthe shaft for rotation'in thebushing.---v Various arrangements for ball bearing support of the inkingroller have'been suggested without success in view of the necessityfor-frequent removal of the same. Itis an object of my invention toprovide an attachment permitting use of a ball bearing assembly. v

A still further object is to provide an attachment which may be readilyapplied to inking the inking roller'from' a press.-

roller shafts already in use on existing newspaper press installations.v

A further and specific object is to disclose an attachment"construction'in which the bearing assembly may be lubricated withoutremoval'of Other objects and advantages of the invention will beapparent from a consideration of the following specification inconjunction with the accompanying drawings, in which:

Fig. 1 is a sectional view of one form of-attachmentsupported in aroller bracket withan inking roller shaft mounted therein; 1

Fig. 2 is anend view of the bracket holding the assembly;

" Fig. 3 is a view similar to Fig. 1"sho wing a 'mo'd- 'ified attachmentstructure;

Fig. 4 is a similar, view of another modification of said structure; and

Fig. 5 is a similar view of still another form of attachment structure.v

' A usual mountingbracket I (Fig; zlis'attached to the" frarne of anewspaper press tosupport one endof an inking roller shaft, as will bereadily understood by those skilled in' the art. A similar bracket (notshowmlsupports the other endof the shaft. 'The holding means for theshaft comprises lower member 2 'witha" lower socket half 3 providedthereinwith a cap 5 pivotally 'joined as at- 4 to member 2 Cap 5 isprovided with an upper complementary socket half 6. The .cap is held inclamped positionby a wing nut and bolt assembly I pivoted asat 8 onmember 2. A slot 9 is provided in the cap to receive'the pivoted bolt inthe clamping relation The clamping arrangement as thus far described isof the, usual construction. 'Forsup-J portingthe end of aninking'r'ollershaftg however, in prior art construction, a split bushingis generally provided with each half thereof mounted'in socket halves 3and 6. The bushing supports a reduced end of the roller shaft forbearing support therein. The bushing as will be seen is notnecessary tothe combinationof and dislodging of bearing balls.

sembly [5. The bearing 15 is adapted for insertion as by a press fit andas shown carries the reduced stud end l5 of an inking roller shaft I!for rotation therein. In this form of the device as in the other formsherein described the bearing as at [5 has an inner and outer race withantifriction rolling elements therebetween. The outer race supplies thestationary load support portion and the inner race supplies the loadmoving part of the bearing, the load moving part receiving the end ofthe roller shaft as at It,

. the -sleeveis restricted by a stop pin l9-fixed in the wall of thesleeveadjacent its opening, the pin projecting inwardly to lie in thepath of col- -lar 13 between inking roller and the collar. .Pin 19 isthreaded in the sleeve wall and is removable to permit withdrawal of theshaft for purposes of repair.

The provision for limited angular movement of vthe sleeve axis withrespect to the axis of the roller shaft 1! permits removal of the inkingroller from the press without buckling of the shaft support at thejuncture of the bearing and roller shaft. In prior instanceswhereballand roller bearings have been installed as the journal connection for aninking roller shaft the removal of the clamping means has resulted in abuckling and twisting at the bearing socket connection thus causingdisplacement of the-bearing races The weight of the inking roller andgenerally inaccessible position of the sameion the press for manualsupport of-the'shaft immediately adjacent the roll :cylinder portioncauses a severe strain at the bearing connection whenever the axis ofthe bearing is not held in alignment with the roller shaft axis. Removalof a clamping member such as cap 5 of course releases its hold on amounting stud whenthe pressmen are preparing to lift the roller fromthepress.

It will. be appreciated that with the special structure herein describedthe mounting stud H will bemaintained substantially in axial alignmentwith the roller shaft l1 Whether clamped in the socket of the bracket orlying free of cap 5. It will be further appreciated that the specialstructure as described may be readily adapted to inkingrollers alreadyin use on existing news paper, press installations. An ordinary rollershaftmay be machined to provide a tip end as shown by Fig. 1 and theattachment assembly coupled on1the end of the shaft. A modification ofthe structure of Fig. 1 is shown by Fig. 3. It comprises several partswith a stud 2| for mounting in a bracket, a collar 22 fitted on theinner end, of the stud and provided with" exterior threading to receivethe internal threading of an elongated sleeve 23 encasing the endportion of the shaft 24 of the inking roller 25. 'An inner shoulder 26of the sleeve recess holds ;a bearing 21 between the shoulder and thecollared end of stud 2!. The end of shaft 24 is journaled in thebearing. Spaced from the end of the shaft and adjacent the opening ofthe Shaft I! and collar l8 are sleeve a radially extending pin 28 isfixed to the shaft. An inturned flanged portion 29 of the sleeverestricts Withdrawal of the shaft outwardly of the sleeve, the shaft pin28 acting as a stop. The flange 29 being spaced slightly from theadjacent surface of shaft 24 acts to restrict angular movement-of thesleeve axis and'maintains the bearingalignment whetherstud 2 i isclamped in the socket or not. A slot 30 in the flange is provided forremoval of the shaft 24 by permitting passage of pin 28 through thesame.

. Fig. 4 shows a further modification of the structure of Fig. l. Amounting stud 3H for hold- .ing the attachment in the fixed support isprovided with a *circular cross-head or collar 32 at its inner end. Thecollar is threaded into an enlarged end opening of an elongated sleeve34.-

The stud 3| is held securely in the opening by a lock nut 35. A shoulder36 between the opening and the main portion of the sleeve 34 provides'an abutment against which the outer race 36 of aball bearing assembly isheld by the face of cross-head 32. A reduced tip end '38 at the outerend of inking roller shaft 39 is encased by the inner r ace of thebearing.

7 A radially extending pin is turned in the Wall oi -sleeve adjacentinking roller 4| and is positioned between the walls of an annulargroove '42 in the shaft 39. A lubricating channel 43 in the stud 3|leads from a lubricant fitting 44 on the outer end of said stud to arecess 45 in the inner face thereof for convenient lubrication of thebearing assembly 37 without the necessity of removing theattachment-from the stud 3|.

The radial pin 40 with a reduced tip 46 permits free rotation of shaft39 with the tip spaced from the walls and bottom of the groove 42. Thepin will positively prevent relative longitudinal movement of the shaftand sleeveon-removal of stud 3| from the clamping cap and socket of thebracket. The pin may be removed if desirable and the frictional holdofthe inner bearing race on' the reducedend 38 may serve alone tomaintain the shaft securely held by the bearing against relative;longitudinal movement. The outer race. or bearing support is held by apress fit within the cylindrical portion-of sleeve 34 between theshoulder 36 and cross head 32. The end 38 is forcibly inserted'in theinner race or load moving part with a tight frictional force fit and thebearing assembly itself is of suflicient strength to prevent ordinarylongitudinal slipping of the sleeve with respect to the shaft.

Fig. 5 shows a form of attachment construction adapted for a pressinstallation wherein limitations of spacing between the mounting bracketclamp and the end of the roller do not permit the use of a sleeveportion in the man.- ner of Figs. 1, 3, and 4. The mounting bracket Iis'positioned in relatively closely spaced relation to the face end 41of an inking roller. A stud 48 held in the bracket 1 has sleeve portion49' carried integrally at its inner end.

"A ball bearing assembly 5| is inserted as by a present in the inner endof sleeve 49 to surround a shortened end 52 of the inking roller shaftrotatably held in said bearing. A lubrication channel 54 and a fitting55 at the outer end of the'stud 48 is for lubricating the bearing.

In" this form of attachment the outermost end of sleeve dsfisreceived inanannular recess 56 cut in the face end 41 of the roller. Thisconstruction of the attachment contemplates the modification of theroller end face so as to provide a shaft portion as at'a shelf 51. Therecess cylindrical surface of sleeve ,49 at the outer end thereof isclosely spacedfrom the annular shelf .51: formed by the recess 56.i Theend 52 is-inserted forcefullyand tightly: fitting the same in thebearing, as by driving the inner race over said end so as to resist anyordinary tendency to vbeishifted longitudinally. In lifting the. rollerby the" stud the outer sends-of the sleeve portion 4% bear :against' theshelf ,51"-=.tocprevent a sharp angular twisting of-the bearing-parts..'It will be seenlthat the various forms'of attachment described may be:used' in converting existing roller-shaft assemblies on various typesof newspaper presses.
